U.S. Sen. Bob Corker has made it clear he won’t run for president in 2016. But could he be in the running for a high-profile Cabinet position in the next presidential administration?

His Tennessee Senate colleague calls him an “obvious choice.”

In this week’s Time magazine, which named Corker one of the world’s 100 Most Influential People, Alexander glowingly wrote about Corker. He traced the junior senator’s recent deals on debt, financial regulation, immigration and Iran, calling Corker “a conservative who prizes results over speeches.”

“His tough-minded pragmatism and grasp of economics have restored prestige to the Foreign Relations Committee and are reminiscent of George H.W. Bush’s skilled team,” Alexander wrote. “If he is not President himself, Corker is an obvious choice for Secretary of State or Treasury.”
